BROODER.

Specification of Letters Patent.

Application filed May 15,1906. Serial No. 260,382.

To all whmn it may concern.-

Be it known that I, PETER A. CHIPPEN- DALE, a citizen'of the United States, residing at Auburn, in the county of Androscoggin and State of Maine, have invented new and useful Improvements in Brooders, of which the following is a specification.

This invention relates to improvements in brooders and is especially designed to provide a brooder in which the temperature is kept uniform at all times and also one in which the air can be and is frequently changed Without affecting materially the temperature and without causing drafts.

In the drawings herewith accompanying and forming part of this application, Figure 1 is a Vertical section of my improved device; Fig. 2 is a sectional view of the ventilating pipes which allow the air to be brought into the brooder chamber; Fig. 3 is a perspective view of the brooder and Fig. 4. is an end view showing the means of supporting the water tank over the brooder chamber.

In said drawings A is a case which may be made in any desired form said case being provided with a bottom piece B, top piece C, removable hood D, and a removable boxshaped cap portion K through the top of which extends ventilating pipe J. There is also provided within the casing a floor E spaced above the bottom of the casing and leaving an air space therebetween. There is also suspended from the roof of the casing a water tank F, said tank being so constructed that the same may be easily removed through the front of the brooder, the portion K of the roof being first removed. The means of suspending the tank as shown in the drawings consists of bolts and nuts F said bolts running through the top of the casing and carrying on their lower end cross pieces G upon which the tank rests. Connected with said tank is a boiler H, said boiler is preferably cylindrical in shape and is connected with the water tank F at one end, said boiler is provided with an opening H running from the bottom through to the top. Adapted to be placed beneath said boiler so that the heat generated therefrom may pass through the opening in the boileris the heater. As shown in the drawings a lamp I is used for the purpose, the same being placed in a compartment I separated from the brooder chamber. Running from the opening through the boiler through the water tank and from this to ventilator J connecting with the outer air is a smoke flue K, the lower end of the ventilator J loosely and removably engaging the end of flue K, the removal of cap K and ventilator J permitting the removal of the water tank through the opening formed by such removal. This flue serves the double purpose of carrying off the fumes from the lamp, causing a proper draft so the lamp will burn and also serves as an additional means for heating the water in the tank. Said opening in the boiler is also provided with a cover L. Directly beneath the tank is the brooder chamber proper. Running into said chamber and connecting it with the outer air are ventilating pipes M and N, said pipes being divided in the center by a vertical partition 0 as shown in Fig. 2 of the drawing, the outer openings of said ventilating pipes M and N being covered with porous material. This partition is used to insure the admission of fresh air into the brooder chamber and to prevent a current of air blowing directly across the pipes and not entering the brooder chamber which would happen if "the vertical partition were not so placed, especially so in case the brooder was placed where the wind was blowing across it.

The top of the case is provided with an opening P for the purpose of allowing the su.-

perheated and foul air in the brooder chamber to escape. The top of the casing is also provided with an opening Q with a funnel or some other suitable means for filling the tank with water when the water therein becomes exhausted. At one side and near the bottom of the casing I provide a port R to allow fresh air to be admitted into the heating chamber I. There is also provided a door S at one end of the casing opening into the heater chamber so as to enable the operator to get at the lamp and trim and fill the same. Said door is provided with an opening S for the purpose of admitting air to the heater chamber. This opening is covered with cloth. or other porous material V. The opening in the door co-operating with the port R supplies ample fresh air for the heating chamber, causes the steady draft upwardly through the lamp and by means of the openings being covered by cloth there is no danger of sudden gusts of wind extinguishing the lamp. The opening between the floorof the thereby keeping the floor ol' the brooder chamber at a more nearly uniform temperature, especially also for the reason that as said opening connects with the heating chamber some of the heat generated by the lamp must of necessity enter the space between the brooder chamber floor and floor of the casing. In order to regulate the temperature of the brooder chamber, I employ an automatic regulator which consists of two expansible disks mounted in a bracket T which bracket is attached to the wall of the brooder in any suitable manner. Mounted on said bracket is a tube U. In said tube is a vertical rod V which. rests on the expansible disks. On the top of the brooder casing and concealed by the hood thereof is a pivoted rod W carryin on one end a hooked arm 1. Suspended irom said hooked arm is a cover L adapted to fit over the opening II in the boiler. About midway of said arm is an adjusting pin 3 which pin is adapted to rest upon the top of the vertical rod V. On the other end of said rod W is a counterpoise weight 4. Also mounted on the top of the v casing is a rod 5 pivoted in any suitable manner as seen at 6, said rod carrying on one end a hook 7 and a cover 8 adapted to close the opening P in the roof of the casing. Said arm also carries on its other extremity a counterpoise weight 0. The purpose of these is as follows. When the heat in the brooder chamber is greater than is desired, that is, when the temperature rises above a predetermined point, the disks expand, cause the vertical rod to rise in the tube and by so doing force the rod W upwardly. This lifts the cover from the opening in the boiler and allows the heat to go directly into the hood. By so lifting the cover the end of said rod W carrying the counterpoise weight is depressed. This in its turn allows the rod 5 carrying the cover which closes the opening P in the top of the casing to be depressed causing the cover over the opening I? in the top of the casing to be raised by such process. The warm air in the brooder naturally escapes into the hood and thence outwardly through the openings 11 in the roof to the outer air. As soon as the air in the brooder is allowed to escape by means of the cover over the opening in the roof being raised, a

. current is produced which causes air to be admitted through the ventilating pipes M and N and thence carried into the brooder chamber. is consequently changed and the temperature lowered to the predetermined. point. When this point is reached the disks will contract and when said disks are so contracted, the covers are replaced automatically both over the opening'in the boiler and the opening in the casing. In order to prevent sharp currents of air from going into the brooder, I cover the ventilatmg ports M and N with flannel or some porous material.

Having thus described my invention and its use I claim 1. A brooder consisting of a suitable casing having compartments therein, one of said compartments being a brooder chamber, ventilating pipes extending from the outer air into saidbrooder chamber, said pipes being divided by a vertical partition so as to prevent cross drafts, a heater, means for regulating the temperature in the brooder chamber and a removable water tank and boiler suspended from the roof of said brooder for supplying heat to said brooder chamber.
